To all whom iii-may concern Be it known that 1, CHARLES W. HUBBARD, a citizen of the United States, residing at Boston, county of Suffolk, State of Massachusetts, and whose post-office address is vNo. 111 Devonshire street, Boston, Massachusetts, have invented an Improvement in Spinning and Twisting Apparatus, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to spinning and twisting apparatus of that type which is constructed to build up the yarn mass on a yarn receiver in layers extending transversely to the axis of rotation. Devices of this type include a rotating yarn support'on which the yarn is wound, a twisting or winding head comprising a winding plate which rests on the-yarn mass and which has a rotative movement relative thereto, and atraversing member or yarn guide movable radially of the Winding plate and operating to lay the yarn in a definite position on the yarn mass.

The objects of the present invention are to provide an improved device of this nature in which the mechanism of the twisting head is greatly simplified and arranged to occupy a compact space, in'which the difl'eren'tial gearing by Which the thread or yarn guide is given its traversing movement is confined within an oil chamber and can, therefore,-

be operated in oil, thus enabling the device to be run at an extremely high speed, in which novel means'are provided for maintaining a constant tension on the yarn at all times, thus enabling a homogeneofis :yarn mass to be built up; which. is so designed that when the desired amount of yarn has been built up on the yarn mass said yarn can be withdrawn from the yarn mass to be wound on a spool or other device without removing the twisting head from the device, and in which the winding plate which rests on the yarn mass as the latter is built up can 7 also be used as a presser-plate to hold the yarn mass in position as the yarn is being withdrawn therefrom during 'the doffing procem, and otherwise to improve twisting hnd spinning apparatus of this nature, all as will be more fully hereinafter described and "then pointed out in the appended claims.

In order to give an understanding of my invention 1 have illustrated in the drawings'a selected embodiment thereof which will nowbe described.

Fig. 2 is a similar view showing the parts in position for Withdrawing the yarn vfrom the yarn mass;

Fig. 3 is a section on the line a2w, Fig. 2;

'2 with a part broken out.

The yarn support on which the yarn is received is herein shown at 1, it comprising a base 2 on'which the yarn mass is built and side walls 3 which may or may not have openings therein, and which form with the base a chamber or receptacle to receive the yarn mass 4. This particular form of yarn receiver, however, is not essential to the invention. The yarn receiver is shown as journaled in bearings 5 and (i, it having for this purpose a journal or step 7 at its lower end which is operating in the bearings 5, and being provided with a bearing sleeve 8 extending from its upper end which is jou rnaled in the bearing 6. The sleeve or stem 8 is herein shown as secured to the cover portion 9 of the yarn receptacle. The yarn support is shown as driven froma driving shaft 10 means of suitable gearing, that herein shown comprising bevel gears 11 by which a vertically arranged shaft 12 isoperated from the shaft 10, and a gear 13 on the shaft'12 which meshes with a gear 14 on the step 7, said gears thus operatmg to give a positive drive to'the yarn support. As stated above, the yarn 17 is.

laid on the yarn support in layers which extend transversely to the axis of rotation, thisbeing done by a winding or twlstin'g theslot as the Winding loo The winding head derives its rotary movement from a spindle 19 which is shown as square in cross-section and which projects up through the top 9 of the receptacle, through the hollow sleeve 8 and through a gear 20 which is held from longitudinal 'movement while permitting the spindle to ing of t e yarn on the yarn mass.

slide therethrough, and which meshes with and is driven by a gear 21 carried by the shaft 12, said gears 20 and 21 having such relation to the gears 13 and 14 that the winding head will rotate either faster or slower than the am mass thereby to cause the 112%- e spindle 19*is made hollow so that the yarn 17 is led therethrough to the thread guide 16 and the desired twist isgiven to the yarn by reason of the rotary motionof the winding head, as will be obvious.

As the thread mass builds up the twisting head will rise in the receptacle 3 and the spindle 19 will be carried up through the spindle 8 and gear 20, but as said spindle 19 terminates at the winding head, there will be no spindle extending through the yarn mass 4. Inmy present invention I have endeavored to simplify the construction of the winding head so as to enable the parts thereof to occupy a compact space and so as to provide that the gearing and cam mechanism shall operate in oil.

The spindle 19 is secured at its lower end to a yoke 22 that in turn is rigidly secured to the winding plate 15 and thus there isa positive rigid connection between the spindle 19 and the winding plate so that the latter will be driven positively by the gear 20.

The yarn guide 16 is givenits vibratory movement by differential gearing which is driven partly from the spindle 19 and partly from the yarn support. Said spindle 19 extends through a sleeve 23- which is noncircular in cross section and which, therefore, fits the spindle, but is slidably mounted thereon, and said sleeve has secured to its lower end a casing ,24 in which the differential gear and cam mechanism for operating the yarn guide 16 are inclosed. The yarn guide 16 is carried by the end of an arm 25 which isdetachably secured to a member 26 pivoted at 27 to the casing 24, the inner end of said member 26 having connection.

with a sliding actuator 28 that extends into the casing and is provided with a roll'29 operating in a cam groove 30 of a cam mem-' ber 31, so that rotation of the cam 31 will cause the vertical movement of the actuator 28 thereby oscillating the yam guide 16. The cam member 31 is rotatably mounted upon a sleeve 32 which incloses the sleeve 23 and which is arranged tobe rotated with the yarn support. To accomplish this the sleeve 32 is shown as secured at its upper end to a head'33iwhich is received within the recep- 'tacle 3 for vertical movement, butrotates therewith. Thus when the machine is in operation the casing 24; will rotate with. the spindle 19, while the. sleeve 32 \will rotate .with the yarn support. The rotary movement of the cam 31 is derived partly from the rotation of the spindle 19 and partly from the rotation of the sleeve 32 and the means herein shown for givin rotation comprises a gear 35 rigid with the sleeve 32 and rotating therewith, a-second gear 36 rigid with the cam 31 and situated casing 24 with the gear 37 is rotated at athe cam its different speed by the spindle 19. Thus the gear 37 will be'carried around" the rotating gear 35, and as the gear 36 has a difierent number of teeth from the gear 35',the result v will-be that the gear 36 will be given a rotary movement relative to ,the gear 35, thils turning the cam member 31. The casing 24 is made oil tight and is designed to contain oil for lubricating the gearsand the cam; andthus these parts may be run in oil. The shape of the casing is such that there is no danger of oil being. thrown out therefrom during the operation ofthe machine. Further, the cam and gear construction of the winding headis compact and occupies but a small space. p y

In laying yarn by a twisting head of this type'wherein the yarn guidefmove'sradially of the yarn mass, the yarn will be laid more" rapidly when the thread guide is at the periphery of the yarn mass than when the thread guide is near the center thereof, andthus the .movement of the thread guide toward and from the center would tend to produce an uneven tension on the yarn, the tension being greatest when the yarn is being laidv on the periphery and least when being laid near the center. In order to obviate the disadvantagesa inherent in a structure where the yarn is thus subjected to varying tension, I have provided a, novel compensatingdeyice which acts on the yarn between its delivery from the spindle 19 and the yarn guide and which serves-to vary .the tension on the yarn as required to compensate for the uneven tension produced by the vibrating movement of the yarn guide. This compensating devlce is shown in the form of'a compensating arm 40 having an eye 41 throu h which the yarn passes and which, is piv ted at 42 'on the casing, the inner end of said arm meat ' and which is provided with a roll44 operating ina cam groove formed in the cam member 31. The cam groove 45 will be so designed as to give the compensating arm 40 therequisite movement to compensate for the varying tensionwhich would .be produced in the yarn by the movement of theyarn guide 16. When the yarn'guide 16 is moving toward the center of the mass the. compensating arm 40 will be moving outwardly, thus drawing on the yarn and forming a loop-46 therein, while when the yarn guide 16 is moving in the opposite direction or toward the periphery the compensating arm will move inwardly, thus giving up the yarn of the loop 46. By this means the yarn will be drawn through the spindle 19 at a uniform rate of speed and the tension thereon will be constant.

The present invention is so designed as to I permit the, withdrawing of the yarn from the yarn mass and without removing the twisting head from the receptacle, so that with this device it is possible to spin yarn and lay the spun yarn in a thread-mass in the receptacle 3, and when the desired amount of yarn has thus been accumulated, the yarn may be removed from the eyes 41 and 16 (they being made inthe form of open eyes for this purpose), and the end of yarn led out through the hollow spindle to a spool or other receiving device and thus withdrawn from the receptacle 3. During this operation the receptacle 3 may be rotated so. that additional twist may be put into 7 the nyarn while it is being withdrawn therefro The advantage of this is that apart only of the desired twisting need be put into the yarn when it is led into the receptacle 3, as the remaining amount of desired twist can be put into the yarn as it is being withdrawn from the receptacle 3.

In order to permit the yarn to be with-- drawn from the receptacle 3 while the latter is being rotated and yet to hold the various layers of the yarn mass m operative position, it is necessary to employ a presser-plate which rests on the yarn mass as the yarn is being withdrawn therefrom. In my present invention I use the same plate 15 as the winding plate for winding the yarn onto the yarn mass 4 and'as a' presserplate for'holdin'g the top layer of yarnmass in position as the yarn is withdrawn therefrom.

In winding yarn into the receptacle 3, it is desirable to have a greater weight on the winding plate than is necessary on the presser-plate when yarn is being withdrawn from the yarn mass. In the present embodiment the weight on the winding plate 15 when yarn is being wound onto the yarn mass comprises the weight of the casing 24 with the gearing and cam therein, the welght to suit the requirementsof use. In order to enable the same plate 15 to be used as a presser-plate when the yarn is being unwound or withdrawn from the yarn mass, 1- have provided herein a construction by which the weight of the parts 50, 33 and the gearing and cams for operating the arm 25 can be removed from the plate 15 so that the yarn mass will, be subjected only to the weightof the plate 15 and the spindle 19. I accomplish this by making the sleeve 23, casing 24 with the arms 25 and 40, sleeve 32, and head 33 with its weight 50 so that they move as a unit and can be. raised or lowered on the spindle 19. The lower end of the casing 24 is not connected to the yoke 22, but merely rests thereon when the parts are in position for winding yarn onto the yarn mass, as shown in Fig. 1.

1When it is desired to unwind or withdraw yarn from the yarn mass 4, the casing 24 with its associated parts is raised upon the spindle 19 so that its weight is removed from the plate 15 and the yarn end'is then led 'fromthe slot 18 into 'a central aperture 51 formed in the plate 15, from'which it is withdrawn, said yarn passing up through the spindle 19, see Fig. 2. In order to per mit the ready threading of the yarn into the,

central aperture 51, I propose to extend the slot 18, asshown at 52,.to cause it to enter the aperture 51, the poition 52 of the slot having a general spiral shape. This enables the yarn end to be readily carried from the, traversing slot 18 around into theaperture 51 when the winding operation has ceased and it is desired to unwind the yarn from the thread mass. The shape of the spiral slot '52 is such as to prevent the yarn from passing back into the slot 18 during the unwinding process.

"I have provided herein for supporting the casing 24 with its inclosed parts and the head 33 with its weight 50 from the top 9 of the receptacle 3 when the yarn is being withdrawn from the receptacle thereby holding said parts out of the way while allowing the plate 15 to act freely as a Presser-plate. Any suitable means for accomplishing this may be employed. i As herein shown the head 9 is provided with supporting hooks53 pivoted thereto at 54 andwhich depend therefrom, said hooks being adapted to interlock with the weight 50 when the latter is raised, as seen in Fig. 2, thereby to hold the parts assdciated with the weight 50 and head 33 in their elevated inoperative position. The weight 50is shown as provided with an annular opening 55 and with an annular flange 56 at the periphery of the opening with which the supporting hooks 53 engage. The hooks are acted upon by suitable springs 57 so that when the head 33 and the weight are raised the hooks will automatically enter the opening and-become interlocked with the flange 56.

In order to disconnect the hooks from the flange '56 it is necessary to first raise the weight slightly and then to force the hooks inwardly, and this latter operation is accomplished by means of a cam 60 which is loosely mounted on the top 9 of the receptacle and is provided with cam projections 59 adapted to engage the shanks of the hooks 53 when the cam member is turned. This cam member is shown as having a rim portion 61 which may be grasped toturn it, and its turning movement relative to the top 9 is limited by slots 62 formed therein through which pass pins or screws 63 that enter the top 9. The disengaging of the hook from the flange 56, therefore, involves raising the twisting head slightly and then operating the cam member 60 to force the.-

hooks inwardly,

The eyes l6and 41 are preferably open eyes or hooks so that the yarn can be easily threaded ,into them or removed from them as occasion necessitates.

While I have illustrated herein a selecte embodiment of my invention I do not wish .to be limited to the constructional features shown.
